[Math] Finding the area of an irregular shape

area

This is probably a stupid question but if I have the number of sides of an irregular shape and the length of each side is there a way to find out the area the shape without knowing what the shape is? i.e. I cannot use the method of breaking the shape into small regular shapes such as rectangles, triangles, etc. to calculate the total area.

The only information I have is the number of sides and the length of each side. Many thanks for any help!
